Thanks! Its been driving me crazy to try to crack it. It cant be this easy right.....? I thought a lot about the possible starting point for the algorithm, but i found having it just be "unknown" like this was all that was needed. A test to make sure, pos_a, pos_b, pos_c are never the same might be useful. The code obviously needs to be fixed to modulo pos_X never to be larger then the key size.
